| Anti Freeze Freezing Boil Temperatures |
| Anti Freeze Ethylene Glycol Freezing and Boil Temperatures. Anti Freeze ( ethylene glycol and propylene glycol ), when not diluted with water, are actually less corrosive than water is with common construction metals. |

| Emittance of Commonly Used Materials |
| Thermal emittance refers to the ability of a material to radiate the heat that it absorbs. It is described through a number varying between 0 and 1, representing the comparative/relative emittance with respect to a blackbody operating in similar conditions. |
|
| Thermal Expansion of Metal Pipe |
| Temperature changes cause dimensional changes in all materials. Table 1.0 shows the coefficients of expansion for metallic piping materials. For systems operating at high temperatures, such as steam and hot water, the rate of expansion is high, and significant movements can occur in short runs of piping. |

| Heat Gain from Lighting Calculator |
| The energy emitted by lighting and then absorbed by the structure and contents contributes to space cooling load only after a time lag, some still reradiating after the heat sources have been switched off. |

| General Ventilation Rates Table |
| Listed below are general ventilation rates for some common applications. Where more than one method is shown use the method that results in the higher airflow rate. |
